摘　　要：氯磺隆,甲磺隆,乙磺隆和亚磺隆等是一类新型、高效、低毒、广谱性的磺酰脲类超高效除草剂。本文报道磺酰脲类除草剂的高效液相色谱分析法。色谱分离柱为Lichrosorb Si-60,20×0.3cm I.D.不锈钢柱;流动相为石油醚/异丙醇/甲醇/乙腈/氯仿(70:10:10:5:5,V/V)混合溶剂,1ml/min;紫外检测波长254nm;样品峰的保留时间值:6～15min;最低检出浓度:2～10PPb;回收率达91.92～97.68％,适合于工业产品及水、土壤、稻苗和稻米中残留量的分析测定。Chlorsulfuron, metsulfuron, classic and bensulfuron belong to a new type of high power, low poison and hroad killing sulfonyl urea herbicides. A high performance liquid chromatographic method was developed for both analysis of their industrial products and residue determination, using a Lichrosorb Si-60 20×0.3cm I. D. column, with mobile phase of petroleum ether/isopropanol/methanol/ethyl nitrile and chloroform mixture solvent (70:10:10:5:5, v/v), 1ml/min. The eluant was detected by UV absorption at 254 nm. The retention time was 6～15 rain and detectable limit of concentration was 2～10 ppb. The recovery for residue determination of extracts from water, soil. rice stem and grain was 91.92～97.68%.
